Bernina L850 Air Thread Serger Demo Model

This machine was used for demonstration purposes only.

THE ONE-STEP BERNINA AIR THREADER

The looper threads are magically moved through the machine by air with one simple step on the foot control. Now both hands are free to guide the threads. The L 850 automatically sets the loopers in the correct position of the air threader – no turning the handwheel or searching for the right position.

Key Features:

• One-step BERNINA Air Threader: Effortlessly threads both loopers with a single step, activated via the foot control, allowing both hands to remain free. [Source]
• Extremely Fast and Quiet: Achieves up to 1,500 stitches per minute with a DC motor, ensuring strong, consistent, and precise stitching at any speed. [Source]
• Total Stitch Control: Individually adjustable settings for thread tension, cutting width, stitch length, and Micro Thread Control (mtc) for perfect seams. [Source]
• Grand Sewing Space: Offers 5 5/8" (143 mm) to the right of the needle and a workspace height of 3 3/8" (86 mm), providing ample room for large projects. [Source]
